To all w hom t may concern.' y

Be it known that I, CARL GUs'rAvn GRON- QUIs'r, a subject of the King ofSweden,

(who have declared my intention of becom-v and is more especially,though not exclu. slvely, concerned with means to clear awayaccumulation of dust, dirt and other foreign matter preparatory to theintroduction of the oil, so that no foreign matter shall be carried intothe oil passage.

My invention will be best understood by reference to the followingdescription,when taken in connection with the accompanying drawings oftwo illustrative embodiments thereof, while its scope will be moreparticularly pointed out in the appended claims.

In the drawings: v

Figure l is a plan ofan oiling device embodying my invention, showingthe same as it appears when closed; y'

Fig. 2 is a plan of the same showing the device as it appears when openfor the introduction of oil;

Fig. 3 is a sectional view on line 3-3 of Fig. 2; p

Fig. 4 is a sectional view on line of Fig. 3;

Fig. 5 is a plan of another form of oiling device embodyingmy invention,showing the same as it appears when closed;

Fig. 6 is a plan of the same as it appears when open; and f l Fig. 7 isa sectional view on line 7--7 of Fig. 6.

Referring to the drawings, and to the embodiment of 'my invention whichis llustrated in Figs. 1 to 4, inclusive, I have there shown an oilingdevice comprising two relatively movable parts 8 and` 9, having normallynon-registering openings 10 and 11, which may be brought intoregistration to permit the introduction of oil therethrough into apassage 12, which may be, and in the present example is, a chamber orreservoir for supplying oil through a passage 13 to a bearing surface14. It should be understood, however, that my invention is by no meanslimited to an oiling device of any particular class or to thelubrication of bearings of any particular kind, but thatfit issusceptible of very general application.

The part 8 may be mounted'tomove in any suitablemanner on the part 9,but inf the present example is mounted to turn thereon, and is arrangedycoaxially with re' latlon thereto. The outer opening 10 isv elongated inthe direction of travel, as best shown in Figs. 2 and 4, and is formedsub-l stantially concentric withthe common axis of the parts 8 and 9.Imay provide any suitable means movable lengthwise of the elongatedopening 10 to clear the latter of foreign matter preparatory to theintroductionv of the oil, butin the present example, I haveshown a pin15 secured to the part 9 and projecting into said slot.` In the presentinstance, this pinis snugly fitted into a hole 16 in the inner part 9,and, asan addi# tional measure of precaution, to prevent the` pin frombeing dislodged, I have herein provided the same with lateralindentations 17,

into which spurs 18, formed of the metal of the surrounding part 9, maybe ldriven by a suitable implement, thereby to interlock with the pinand prevent the same from drop? ping out.

If now, when the devicefis closed,.there arek any accumulations of dust,dirt orother l.

foreign matter in the outer opening 10,`when thek outer part 8 is turnedto expose the inner opening 11 for the introduction of oil,

the pin 15 will traverse the outer opening and clearsuch opening of theaccumulation of foreign matter, so that there will bel no danger of itsentering the opening 11. The

pin 15 performs two other functions,-tirst,

it coperates with the slot 10 to limit the relative movement of theparts 8 and 9: and second, itprevents separation of said parts. y

If desired, there may be providedsuiu able means tending' to resistturningmove-v ment of one part upon the other, and in the presentexample, I have shown for this purpose a spring 19 bearing at one endagainst the inner. face of theouter part 8. The other end of this springbears against a cap 20,2

which closes the outer end ofthe passage 12. This spring tends tourgethe part 8 in an outward direction on'the part 9, and since suchmovement is prevented by the pin the friction of these parts one on theother serves as an effective means for preventing accidental opening ofthe'device.

The form of my invention hereinbefore described is particularly adaptedfor horizontal arrangement, but tlieiorm shown in Figs. 5, 6 and 7, isespecially adapted for use in an upright position. Referring to thelatter form, I have shown anoiling device comprising outer and innerparts 2l, and 22, arranged to turn one on the other, and provided withnormally non-registering openings and 241, which may be brought intoregistration to permit the introduction of oil therethrough. In thisform, the oil is introduced through these openings into a chamber 25,constituting` a reservoir formed in aseparate part 26 onto Which thepart 22 is threaded. A standpipe 27 mounted in the part 26 and extendinginto the reservoir4 receives oil from the latter by means ot a wick 28,which feeds the oil by capillary action to passages 29 and 30, by meansof which it is delivered to a bearing surface 31. It should noiv beapparent that the inner opening 2li is normally closed by the outer part21, as shown in Fig. 5, and that when the latter is turned to theposition shown in G, the openings 23 and 24 are brought intoregistration, and in so doing a pin 32 secured to the inner part andprojecting into the opening in the outer part clears such opening of anyaccumulations of foreign matter, and prepares. the openings for theintroduction of the oil. In this form, the pin serves also as Va meansfor limiting relative turning movement ot the parts 21 and 22.Separation of these parts, however, in this example is prevented by asuitable fastening element, preterably in the form of a rivet 33 whichpasses axially through the parts 21 and 22, as best shorvn in Fig. 7,and thus prevents accidental separation of these parts.

lVhile I have herein shoivn and described two specific forms orembodiments of my invention, and have disclosed and discussed in detailthe construction and arrangement incidental to tivo specic applicationsthereof, it is to be understood that the invention is limited neither tothe mere details or relative arrangements of parts, nor to its speciiicembodiments therein shown, but that eXtensive deviations from theillustrated forms or embodiments of the invention may be made, Withoutdeparting from the principles thereof. p

I-Iaving thus described my invention, What I claim and desire by LettersPatent to secure is:

l. In an oiling device, the combination of inner and outerrelatively-rotatable co-aXially-arranged parts having normallynonregistering openings which may bebrought into registration Jfor theintroduction of oil,

the opening in the outer part being elongated and formed substantiallyconcentric with the common axis of said parts, said inner partpresenting a reservoir entirely therein, and means carried by the innerpart adapted to traverse such elongated opening to clear the same oflforeign matter preparatory to the introduction of oil.

2. In an oiling device, the combination of an inner part provided withan oil passage and an opening communicating therewith, an outer partcomprising a cup-like cap having a sleeve portion `encircling andmounted to turn on the outside of said inner part and provided With acircumierentially elongated opening, which in one position of saidsleeve registers with the opening in said inner part and in anotherposition is out of registration therewith, and means o n said inner partprojecting into said elongated opening and traversing the latter Whensaid cap is turned to carry said elongated opening into and out otregistration With the opening in said inner part.

` 3. In an oiling device, the combination of an inner part provided withan oil passage and an opening communicating therewith, an outer partcomprising a cup-like cap having a sleeve portion encircling and mountedto turn on said inner part and provided with a circumferentiallyelongated opening, which in one position oi' said sleeve registersrviththe opening in said inner part and in another position is out ofregistration therewith, and means on said inner part pro liecting intosaid elongated lopening and traversing the latter when said sleeve isturned to carry said elongated opening into and out of registration Withthe opening in said inner part, saidmeans also limiting the turningmovement o'f said cap and preventing said cap from being Withdrawn fromsaid inner part.

In an oiling device, the combination of inner and outer relativelymovable parts having normally nonnregistering openings Which may bebrought into registration to permit the introduction of oil therethroughinto the inner part, said outer part compris ing a cup-like cap mountedto turn on the inner part, said openings, when registering, providing apassage extending transverse to the direction of their relativemovement, the outer opening being elongated in the direction of suchmovement, and means carried by the inner part to clear said elongated'opening of foreign matter preparatory to the introduction of the oil,said means being normally positioned at one end of said elongatedopening and having a movement 'therein substantially equal in extent tothe spacing of said means yand said inner opening.

In testimony whereof I have signed my name to this specication.

Gusravn Gnonouisr.
